  • cover means 10 for covering the exposed adjacent sidewalls of the display panels is provided.
  • a longitudinal groove 60 is formed on the sidewalls of the panel housings so that the cover means 10 slides into or out of the panel housings 20 and 40 along the groove 60 .
  • the multi display device can realize a large-sized screen by connecting plural display panels.
  • the device When the device is unfolded, one sidewalls of the panels disposed to be adjacent to each other, thereby minimizing the non-display area.
  • the device when the device is folded, since only the one sidewalls are exposed outside and other portions are received in the device while being stably supported by the support, thereby preventing the display panels from being damaged by outer shock.
